Corona treatment pens are primarily used to detect partial discharge in high-voltage electrical equipment. Their advantages include ease of use, affordability, and the ability to perform tests without power outages. Therefore, they are widely used in electrical equipment maintenance and safety management.
In addition to detecting partial discharge in high-voltage electrical equipment, corona treatment pens can also be used to measure electromagnetic field strength and the safe distance of electromagnetic radiation, thus finding applications in fields such as electronic communications and radio technology.
